[alsa-devel] [PATCH] ASoC: tegra: utils: Don't use of_have_populated_dt()

[Stephen Warren]

From: Stephen Warren <swarren at nvidia.com>

Recent list discussions concluded that drivers should not be calling
of_have_populated_dt(), and hence of_have_populated_dt() should not be
exported. Use a different mechanism to detect DT vs. non-DT boot.
